Yamaha RX-A4A: Superior AV Receiver with 7.2 channels, Wi-Fi & Bluetooth

The Yamaha RX-A4A uses the Qualcomm® QCS407 chipset to deliver superior sound quality and support Dolby Atmos and DTS:X for a cinematic experience and superior audio performance with DSP technology. Featuring ESS Technology’s SABER ES9007S Premier DAC for exceptional signal-to-noise ratio and up to 120dB dynamic range, the AV receiver delivers professional-quality digital audio.

SURROUND:AI technology uses artificial intelligence to analyze the configuration of audio sources in entertainment content and optimize the surround sound of individual audio elements such as background music, dialogue and sound effects. The effect is as if a professional Yamaha engineer is tailoring the sound just for you. The receiver supports the 64-bit Qualcomm® QCS407 chipset.

The Yamaha RX-A4A also features Yamaha’s Cinema DSP HD3 3D surround sound technology, which is based on a combination of actual measured sound field data and the latest digital signal processing techniques. The updated CINEMA DSP HD3 technology includes new signal processing algorithms and brings sound quality closer to what you hear in movie theaters, creating a realistic sound field that truly immerses you in what’s happening on screen.

The Yamaha RX-A4A receiver uses Anti Resonance Technology (ART) in the form of a special fifth leg, which is located in the front center of the device. It absorbs much more vibration from the power transformer, transistors and heat sinks, as well as possible vibration from the speakers, resulting in dynamic sound and focused, accurate reproduction.

The Yamaha RX-A4A is equipped with Zone2 compatible speaker terminals and can send audio and video content played in the main room for playback in another room (or even play other content in that room). For example, if the speaker is also installed in the bedroom or kitchen, you can move into that room and continue listening to the same content as in the main room (or different).

The Yamaha RX-A4A AV Receiver is equipped with Phono input jacks so you can connect a turntable and enjoy music from your vinyl record collection. The four SCENE buttons can be assigned to different input signals, as well as sound field programs, Music Enhancer, HDMI output and other functions. You can select different sources as input, such as an FM or Internet radio station, a streaming service station, a USB device, or a song on your PC or network storage device. Once you’ve configured all the buttons, simply press the one you want on the main unit or remote control to turn on the receiver and hear your favorite music. The buttons can be reconfigured at any time.

For those who don’t have in-ceiling or upward-firing speakers in their system, Dolby Atmos with virtual height synthesis technology simulates the Atmos experience using forward-facing drivers. Set up up to five speakers to reproduce the effect of two in-ceiling speakers, or use all seven channels to simulate the powerful effect of four in-ceiling speakers. Enjoy a 5.1-channel surround sound system with two additional in-ceiling speakers or two Dolby Atmos height-effect speakers for stunning sound effects for truly immersive surround sound. And Dolby Surround technology will add volume to even older content that did not originally support surround sound.


DTS:X immersive audio formatting technology places sound where it belongs in space, creating a realistic and immersive audio environment. The included DTS Neural:X™ spatial upscaling engine brings greater immersion and realism to your favorite movies.

MHL technology makes it easy to directly connect compatible mobile phones to this AV receiver. Supports playback of images from phones with a resolution of up to 1080p and multi-channel audio. In addition, the receiver charges the connected phone. You can use the remote control to turn playback on and off and perform other basic operations.

The Yamaha RX-A4A’s symmetrical internal layout and completely redesigned circuit boards ensure the shortest possible signal path on each board. The new H-shape design improves the receiver’s cabinet strength and sound stability for crisper, sharper, cleaner playback. Additionally, a redesigned mechanical design helps prevent vibration from being transferred from the transformer to the amplifier circuit. Noise reduction ensures clearer playback.


Install the MusicCast CONTROLLER app on your smartphone or tablet to control your AV receiver and change settings quickly and easily. The same app can be used as a remote control for all MusicCast compatible devices, as well as to control your entire multi-room audio system. Just imagine – you can play your favorite music throughout your home, regardless of its format. From your favorite vinyl records to AirPlay®, from Bluetooth® to streaming music services, MusicCast supports any source, even TV audio. The Yamaha RX-A4A also supports high-resolution formats, including Apple Lossless (ALAC) up to 96 kHz, WAV, FLAC and AIFF up to 192 kHz. AirPlay 2 technology allows you to stream music from Apple Music and other streaming music services to multiple MusicCast devices located in different rooms. Control playback with your iPhone or iPad, pair the system with your HomePod, or simply use voice commands. Explore the world of music with built-in music streaming services. By syncing your playlists and favorite songs between your smartphone or computer and the AV receiver, streaming music services make it easy to listen to your favorite music or discover new ones.

Enhanced Audio Return Channel (eARC) is the next generation of ARC technology found in Yamaha’s industry-leading AV receivers. eARC delivers full-resolution multi-channel audio formats like Dolby® TrueHD and DTS-HD® over your existing HDMI connection, so you can listen to stunningly realistic surround sound and truly immerse yourself in your favorite movies.


The YPAO™-RSC Sound Optimization System in the Yamaha RX-A4A analyzes room acoustics using the included YPAO™ microphone, then fine-tunes a series of system parameters to deliver the best sound in your room. Reflected sound control is used to correct early reflections and ensure studio-quality sound. YPAO 3D automatically optimizes audio settings to create the most immersive 3D sound field with SURROUND:AI, Dolby Atmos and DTS:X. 64-bit frequency equalization provides the most natural room acoustics.
